I had some friends over and they brought their pets. A few weeks later and we're battling fleas. I have a grow tent in the basement. It's intake is from a room downstairs and it exits through a window outside. I'm planning on flea bombing the house and I need to know how to do it without hurting the plants. I was thinking of sealing up the intake but not sure if it's a good idea. The plants are still in seedling stage.
